Quantum computing making ‘tremendous progress’

There has been what one researcher calls “tremendously rapid progress” in quantum computing in the last year. A device for overcoming quantum “decoherence” has been developed at the University of New South Wales, using two phosphorus atoms precisely embedded in a silicon crystal.

Other researchers at Innsbruck University in Austria have achieved a quantum computation using a single trapped calcium ion, the first calculation made on a system proven to be in a quantum state.
